May 19, 2015 17:47 IST

    Storage is a media and methods, which is used to keep information available for later use.

    Computer storage is of two types

    • Primary Storage
    • Secondary Storage

    Primary Storage

    • It is the main memory of computer.
    • It keeps track of current processing
    • It is volatile, i.e., turning the power off erases all of the data.
    • For main memory, computers use RAM or Random Access Memory.
    • These memory chips are the fastest, but most expensive type of storage.

    Main Memory = Primary Storage

    Secondary Storage

    • It is the auxiliary storage of computer.
    • It keeps track of what is not currently being processed.
    • It is the stuff that is ‘Filed away’, but is ready to be pulled out when needed.
    • It is non-volatile, i.e., turning the power off does not erase the data.
    • Auxiliary storage is used for input data and programs as well as saving the result of processing.
